“…In recent years much progress has been made in the development of vertical cavity surface-emitting lasers (VCSELs) for applications in communications [l, 21 and addressable arrays [3]. VCSELs also open the door to wider applications such as laser scanning, laser printing, medical imaging, optical mem- This Letter describes a simple method for reducing the threshold current of a VCSEL, by restricting the lasing area in a controlled manner.…”

Analysis on the channel capacity of a coherent optical subcarrier multiplexing system using optical amplifiers is presented. The performance criterion, that is, the channel transport capability N, is derived in terms of carrier‐to‐noise ratio, input optical power, and optical amplifier gain. It is found that when the gain of the optical amplifier is large, the spontaneous emission noise limits the number of channels that can be transmitted in this system. As an example, when the gain is well above 20 dB and input optical power is −28 dBm, the maximum value of N is 46. In addition, the optimum phase modulation index is also presented. © 1995 John Wiley & Sons, Inc.

The electrical and optical measurements were performed after the laser definition step, to test the uniformity of the device. All the measurements were performed at room temperature without heat sinking using a pulsed current source (200 ns pulse width, I O kHz repetition rate). Light was coupled out from the array through the substrate side. Light output against injection current was measured for all the VCSELs of the array (Fig. 3). The results are summarised in Figs. 4a and b. All the 1024 lasers were operating with a
